Differential current-mode clock distribution

In this paper, we present a differential current-mode pulsed flip-flop (DCMPFF) for low-power clock distribution using a representative 45nm CMOS technology. Experimental results show that the DCMPFF has 47% faster clock-to-output (CLK-Q) delay than a traditional voltage-mode (VM) pulsed flip-flop. When the DCMPFF is integrated with a differential current-mode clock distribution, the differential technique saves 62% and 17% power compared to a conventional VM and a previous current-mode (CM) clock network, respectively.
